Check the interior electrical panel on the driver’s side behind the side trim cover first, as most accessory failures such as power windows, radio, and dashboard lighting originate there. Use a multimeter to confirm voltage presence at each slot instead of relying on visual inspection.
The engine compartment power distribution center is mounted near the battery and contains high-amperage links for systems like cooling fans, ABS, and starter control. Each position is labeled with a number and corresponding rating, typically ranging from 30A to 80A for major components.
Inside the cabin, smaller rated elements from 5A to 25A control electronics including infotainment, HVAC controls, and signal lighting. Remove the cover to access the printed layout chart, then match slot numbers to specific circuits. If multiple systems stop working at once, inspect shared relays and grounding points near the panel before replacing any component.

Use the panel cover chart to match slot numbers with circuits before replacing any component; for example, positions rated at 10A–15A typically handle interior electronics and lighting, while 20A–30A slots often serve power outlets and seat controls. Verify amperage stamped next to each cavity and never install a higher-rated element, as wiring damage may occur.
The under-hood distribution unit contains higher load circuits arranged in grouped rows near the battery connection point. Typical assignments include:
- 30A–40A: HVAC blower motor and climate system
- 40A–60A: cooling fan and engine control modules
- 20A: fuel delivery system relay feed
- Main link: supplies power to interior panel
Test both terminals of each slot with a multimeter while ignition is set to the required position; voltage on only one side indicates an internal break. If repeated failures occur, inspect wiring harnesses near the battery and firewall where insulation wear can lead to short circuits.
Exact locations of interior and engine compartment fuse panels in Chevy Malibu 2015
Open the driver-side door and remove the small side cover on the dashboard edge to reach the interior power distribution panel; it is positioned laterally next to the steering column and slightly above the footwell area.
This cabin-mounted unit is secured behind a snap-on plastic trim and aligned vertically, making slot numbers readable when viewed from the side. Use a trim tool to avoid breaking clips, and tilt the cover outward rather than pulling straight.
Access clearance is limited, so a compact flashlight helps identify numbering and amperage markings. The panel sits close to the body control module, which reduces wiring length between switches and electronic components.
Engine compartment panel placement
The under-hood electrical center is located near the battery on the driver-side fender well. A rectangular lid with locking tabs protects internal circuits from moisture and debris.
Press both side tabs evenly to release the cover; uneven pressure may crack the housing. Inside, larger cartridge-style links and relays are arranged in rows, with labels printed on the underside of the lid.
High-current circuits are grouped closer to the battery connection point, minimizing voltage drop and heat buildup during operation. Thick gauge cables feed directly into this unit from the positive terminal.
Additional access and inspection notes
Check grounding points near both locations: inside the cabin behind the kick panel and under the hood near the battery tray. Loose or corroded grounds can interrupt multiple systems simultaneously.
When inspecting either panel, ensure ignition is off and remove the key to prevent accidental short circuits while handling electrical components.
